The bear minimum
Californians don't screw in lightbulbs, they screw in hot tubs. (I remember this from the 1970s when I was in middle school. It's one of my first dirty jokes)
None. Once the bulb goes out, they replace the house.
How many South Americans does it take to screw in a light bulb? A Brazilian!
A voice from the back of the bar shouts back, "You don't have enough ammo, mate!"
It had muscles.
